Application filed. May 3, 1921.

To all whom it'may concern Be it known that I, JArrns A. TARTE, acitizen of, the United States, residing at Blaine, inthe county of'VVhatcom and State of Washington, have invented a new and usefulDeflecting Damper for Pipeless Furnaces, of which the following is aspecification.

My invention relates to deflecting dampers for pipeless, hot-airfurnaces, and the objects of my invention are: first, to providedeflectors for dividing and deflecting the ascending column of air as itleaves the furnace; second, to adapt said deflectors for control andclosure purposes; and third, to cause said dampers to operate by-passdampers for controlling by-pass, hot-air outlets.

I attain these objects with the mechanism illustrated in theaccompanying sheet of drawings in which Figure 1 is a plan view of thetop of the cold-air inlet and hot-air outlet of a pipeless, hot-airfurnace, and Fig. 2 is a side elevation of Fig. 1 in section on avertical, medial plane.

Similar characters refer to similar parts throughout. Certain parts arebroken away to disclose those hidden thereby.

More particularly: 3 is the casing of the upper part of the cold-airinlet flue. & is a grill covering the same. 5 is the casing of the upperpart of the hot-air outlet flue. The remainder of the pipeless furnaceof which the illustrations show a part is broken away as not essentialto the proper under standing of this invention.

6 is an annular damper seat fastened to the interior of easing 5.

7 is one leaf of a bifold damper hinged on pin 10.

8 is a by-pass damper rigidly'fastened to leaf 7 by arm 9.

10 is a hinge pin mounted in casing 5 located to adapt leaves 7 and 11for closure on seat 6.

11 is the other leaf of said bifold damper.

12 is a by-pass damper rigidly fastened to leaf 11 by arm 13.

14, 14 is a chain or cable one end of which has two branches, each ofwhich is fastened to one of leaves 7 and 11, and both are riven oversheave 15 from which the cable passes through a hole in casing 3 and toa con venient point from which to control said damper where it isadjustably fastened.

15 is a sheave fastened to the under side of grill 4.

Specification of Letters Patent.

Serial No. 466,583.-

16 is a lug on leaf 11 to bear against leaf leaves are normally open,and, in coopera-- tion with bifurcated chain 14, prevents either of saiddamper leaves from attaining a vertical position.

17 is a hot-air, by-pass, outlet pipe leaving flue 5 beneath damper 7,11.

18 is a hot-air, by-pass, outlet pipe leaving flue 5 beneath damper 7,11.

The inner end of pipe 17 is adapted for closure by damper 8 when leaf 7is normally open, and pipe 18 is adapted for closure by damper 12 whenleaf 11 is normally open. Pipes 17 and 18 may find an outlet in thefurnace room, out of doors, or in distant chambers as preferred.

In operation: The positions of the various parts of my device shown infull lines in the drawings are those of normal operation when heating ahouse, leaves 7 and 11 beingnormally open and dampers 8 and 12 closingpipes 17 and 18. All of the hot air from the furnace now passes throughgrill 4:. But it is divided and deflected into two streams by normallyopen yet inclined-damper leaves 7 and 11. It is customary to locatefurnaces of this type in the door opening between chambers. Notinlfrequently the hot air rising therefrom blisters, and otherwiseinjures the casing of said door opening. This undesirable result isprevented by my device as shown.

On releasing cable 14, from its outer-end fastening, not shown, damperleaves 7 and 11 drop by their own weight to their dottedline positons at7 and 11 on seat 6. Simultaneously dampers 8 and 12 pass to theirdotted-line positions at 8 and 12 respectively, fully uncovering pipes17 and 18, and all of the hot air from said furnace must pass outthrough by-pass pipes 17 and 18.

It is easily apparent that leaves 7 and 11 may be retained by cable 14in a partly open position and the hot air divided between said by-passpipes and the main flue through grill 4-.

Having thus fully disclosed my invention, what I claim is new and desireto secure by Letters Patent is,-

1. In a pipeless, hot-air furnace in combination, a hot-air, outletflue; a bifold, deflector damper hingably mounted in said flue near itsouter end and adapted to divide the passing stream of hot air anddeflect the same, and further adapted to close said hot- Patented June6, 1922 air outlet flue; a by-pass, hot-air outlet pipe leaving;- saidhot-air flue below said deflecting damper, and means operable by saiddefleeting damper adapted to keep closed the same, and further adaptedto close said hot air, outlet flue, two bypass, hot-air, outlet pipesleaving said hot-air flue below said de- Hector damper, a damperfastened to each of the leaves of said bifold damper and adapted toclose said by-pass, outlet pipes when the leaves of said bifold damperare fully opened and further adapted to open said by-pass pipes whensaid bifold dam per is closed, and means to operate the leaves of saidbifold damper.
